Hi everyone,

my 2005 H2's engine acts up occasionally and the RPM collapses for a split second so that the whole car shakes a little as if you rode over a small bump. It happens around 1300 and 2000 RPM.

When I bought the car I interpreted it as road bumps so it is not that noticeable. I just happened to look closer as the check engine light lit up on my way home. The error memory says P0332 and P0327 which means that both knock sensors have low voltage. However, the mechanic said it was almost impossible that both knock sensors break.

I would really appreciate your help!

 

i had this same problem on my h2 my mechanic finally figured it out it was the intake manifold there made of plastic so they warp might want to have a smoke test done on it to see if you have air leaks. hope this helps.

 

Thank you, I'll definitely try that!

I have an appointment with an autoshop next week. I'll let you guys know whether and how we were able to fix it.
